The problem asks to find the missing number in a 3x3 grid, where the row totals are given. We have the following numbers in the grid:

| 15  | 12  | 14  |
| 14  | 14  | 17  |
| 9   | 5   | 7   |
| 261 | 130 | ?   |

To solve for the missing number, let’s observe the pattern used to obtain the totals in the last row. 

### First Row:
15 + 12 + 14 = 41  
To get 261, it seems there is a multiplication factor:  
41 × 6.37 ≈ 261.

### Second Row:
14 + 14 + 17 = 45  
For the second row, 45 × 2.89 ≈ 130.

### Third Row:
9 + 5 + 7 = 21  
Now, we need to find the missing total. Assuming a similar multiplication factor applies here:
21 × 10 ≈ 210.

Thus, the missing number is **210**, which corresponds to option (C).
